  • Sock-like neoprene ankle fit - to help keep little nasties out of you shoe and give full ankle mobility in and out of the water.
  • Water repellent mesh – for minimal wet weight.
  • Quick drain zones – to help pump the water out with each foot stride when you hit dry land.

Fantastic shoe. Possibly my favourite yet.

Bought these on recommendation. Wanted an amphibious off-road shoe and thought I'd give these a try. Had to initially return the size 10 I bought as it seemed a bit too big (usually a 10 is just right) so consider sizing down with these. Have used them in the desert, the ocean and in deep mud and so far these have surpassed expectations.

So far so very good

Still early days to give it a 5 star rating, its very close already though.
Really like the optional lace colour-ways, which I went for.
Really comfortable as you would expect and the grip is very good.
I bought these as an every day wear and they haven't disappointed, from walking up muddy hills to walking round the shops.

I am a very happy Chappy.

Four wheel drive for your feet

Vivobarefoot Primus Trail Swimrun

I’ll be honest. This is my first ever purchase of a “running shoe”. When I received and unboxed these shoes I was amazed at how light and flexible they felt. I’ve been running with them for just over a week now and I’m impressed. The sock like ankle grips and hugs the ankle snuggly but not to the point where they rub. The width is perfect for my size 9 feet. They allow my foot and toes to spread naturally. The tread has been great so far on damp leaf-littered trails. Very good grip and the fact that your feet feels as flexible as, well, your bare feet, means that you can adapt easily to changeable terrain. On the beach runs they are fantastic draining and drying very quickly when crossing the tidal channels. Again the low profile tread offers great traction on wet and dry sand. The wonderfully designed low profile pacing system allows for quick on and off if a change up is required.

I really do rate this shoe! An amazing all rounder , great colour-way and suits my multi-terrain needs to a tee.

This is now my third pair of Vivobarefoot treads. The build quality to date is very very good. Wearing my normal everyday shoes now feels weird and I may not go back to those. The natural multi-sensory feedback you get from a pair of Vivobarefoot shoes is unrivalled in my opinion. Great product.
